In this talk, we will first prove the W-entropy formulas for the heat equation associated with the Witten Laplacian on super Ricci flows on Riemannian manifolds. Then we will introduce the W-entropy along the geodesic flow on the Wasserstein space over Riemannian manifolds, and prove its mononicity formula. Observing that there is a similarity between the W-entropy formulas for the heat equation and for the geodesic flow, we introduce the Langevin deformation of flows on the Wasserstein space, and prove an analogue of Perelmans W-entropy formula for the deformation of flows. This is an joint work with Prof. X.-D. Li.
